The Broodcoil

A freestanding abyssal multigenerational dwelling on a flat, compact dark-basalt footing. Its footprint is an asymmetric nearly closed C, open toward the front-right; a continuous thick mineral pressure passage curls horizontally around a flooded exterior swimming court. Seven unequal egg-shaped sealed residential lobes graft onto the outside of the C, largest at rear-left and progressively smaller toward the front-right terminal. Overall width is about twice its height. Each lobe has a continuous rounded shell roof: no terraces or sliced-open rooms. The front-left end forms a thick upturned shell lip above the main oval bronze lock; the smaller front-right end carries a secondary lock. Outer chamber walls carry sparse deep-set circular cast-glass lenses with tiny blue lower-lip culture lights. Bronze clamp bands connect lobes to the passage, with clear service gaps. White mineral ribs descend to three-toed basalt-anchored buttresses; cold-water coral grows only on their fixed shoulders. Inner court walls show smaller individual lock hatches and a scalloped eave with green culture cartridges. The left elevation is a bulky old lobe with pronounced growth ridges and one repaired socket; the right is a descending chain of newer smooth lobes; the rear has small maintenance collars and two planting racks. From above the coiled passage and seven separate swollen roofs remain legible. Barnacle-white shell dominates, bronze is limited to joints and locks, and glazing is small and domestic. The whole building feels like one enormous organism grown through generations, with clear inhabited thresholds and no animal face.
